Transceivers and cables

With the flexibility of the NE1072T RackSwitch, customers can choose the following connectivity
technologies:
For 1 GbE links, customers can use RJ-45 fixed ports with UTP cables for distances up to 100
meters.
For 10 GbE links, customers can use RJ-45 fixed ports (10GBASE-T) with UTP Category 6a or 7
cables for distances up to 100 meters.
To increase the number of available 10 GbE ports, customers can split out four 10 GbE ports for
each 40 GbE port by using QSFP+ to 4x SFP+ DAC or active optical breakout cables for distances
up to 5 meters. For distances up to 100 meters, the 40GBASE-iSR4 QSFP+ transceivers can be
used with OM3 optical MPO-to-LC breakout cables or up to 150 meters with OM4 optical MPO-to-
LC breakout cables. For longer distances, the 40GBASE-eSR4 transceivers can be used with OM3
optical MPO-to-LC breakout cables for distances up to 300 meters or OM4 optical MPO-to-LC
breakout cables for distances up to 400 meters.
For 40 GbE to 40 GbE connectivity, customers can use the affordable QSFP+ to QSFP+ DAC
cables for distances up to 7 meters or QSFP+ to QSFP+ active optical cables for distances up to 20
meters. These DAC cables and AOCs have QSFP+ connectors on each end, and they do not need
separate transceivers.
With multimode fiber optic LC cables, customers can use the 40GBASE QSFP+ bi-directional
transceivers for distances up to 100 meters with OM3 MMF LC cables or up to 150 meters with
OM4 MMF LC cables.
With multimode fiber optic MPO cables, customers can use the 40GBASE-SR4/iSR4 QSFP+
transceivers for distances up to 100 meters with OM3 MMF MPO cables or up to 150 meters with
OM4 MMF MPO cables. For distances up to 300 meters, the 40GBASE-eSR4 QSFP+ transceiver
can be used with OM3 MMF MPO cables or up to 400 meters with OM4 MMF MPO cables.
For distances up to 10 kilometers, the 40GBASE-LR4 QSFP+ transceiver can be used with single
mode fiber LC cables.
The following table lists the supported cables and transceivers.
